Application filed February 11, 1926, Serial N0. 87,728,'and in Germany February 11, 1925.

Brush stocks are sometimes drilled or bored, for the reception of the bristles, by means of a machine. having aplurality of spindles and a plurality of work holders mounted side by side on a carrier or frame and rotatable about their vertical axes, the

frame being arranged to rock. about a shaft opposite the drills. In some known machines the frame carrying the workholders is also movable laterally and vertically parallel with itself. \Vith these machines comparatively difficult and frequent adjustments are required, occupying much time, for the purpose of drilling the holes at different angles and so: on, and even so they do not enable holes tobe drilled at angle'sso acute as may sometimes be desirable.

The object of my invention is to remove these defects, and to this end I provide machine wherein all the work holders are universally movable upwards and downwards, and to the right and left, and can rangement of universally movable work holders, side by side or above each other, can be used also in a machine for inserting the bristles. I p Y According to the invention the frame or carrier on .which the Work holders are mounted is not fixed directly to arms con-:.

necting it with the shaft opposite the tools, as has heretofore been usual, but is con-1 nected to a double armed lever, which is pivoted cent-rally to the armand whose ends form gudgeons for the frame. Thislever enables the frame in addition to-rotating about its longitudinal axis torock about an adjustable pivot remote from the shaft. In-;

eluded with this device are various other mechanisms for ad'usting and fixing the work holders "and tl them.

A machine accordingto my invention is. shown in the accompanying drawmg, III

Fig. 10 an elevation of the: mechanism shown in Fig. 9.

' The frame'lhas guides for the bearings 52 of a horizontal shaft 3, upon which are two sockets. 4, and in these sockets two radial arms 5 are mounted on pivots 6, so. that the arms canswing sideways, as indicated, by

broken lines in Fig. l. Toeach arm 5 there is pivoted a double armed lever 7, having armsof equal length, with gudgeons 8 at the ends thereof, supporting the frame 10 which carries thework holders 9. By means of the levers7 the frame 10 can be rotated about a horizontal axis. It can also be moved sideways by rocking the. arms. 5, and can be raised and lowered by rotating the shaft 3.

Each work holder9 is slidably connected to a plate 11, the plate 11 being rotatable, on

the frame 10. 9 The work holders are connected with each other by means of a rod 13 having eyesengaging studs on the plates 11. One work holder, which belongs to the series but which have marked 14 in thedrawin has fixed to it a slotted guide 15, in whic there-is aslidableand adjustable member 16 (Figs. 7 and 8) having two curved lateral arms and having also atail piece 17 engaging a curved slotted member 18 fixed to the shaft 3. The member-16 has holes 16, with which a stud or pin 19 carried by the guide canbe selectively engaged, to form a pivot about which the work holder; M canbe rotated. Rotationof the work holder 14 about thispivot causes allthe other work holders to rotate. By selection of thehole 16. into which the pin 19 is inserted the radius of rotation of theworkholders, in reference to their vertical, axes, can be regulated, in order to regulate the lateral obliquity of the holes bored.

In the case of somebrush stocksthe holes 1 are drilled at different angles. For thispurpose the guide 15 is provided with, a second pin 20,-and the work holder can be swung alternatively onthe pin 19 and oaths pin- 20, the pin 19 being disengaged in the latter case.

If the work holders are not to rotate about their vertical axes they are locked by means of pins provided for that purpose.

If the work holders are not to rock about the shaft 3, but to move vertically and laterally parallel with themselves, two links 21, 22 (Fig. connecting the frame to a rotatable spider Ql on the shaft, balanced by a weigh 23, are locked by means of a pin 28 actuated by levers 25, 26, 27. To change over from parallel movement to rocking movement it is only necessary to disengage the pin 28.

If the holes are to be drilled at angles more acute than is allowed for by rocking the work holders about the shaft 3 the double armed lever 7 is locked by means of a member 31 which is pivoted to a yoke 29 on the lever and is connected to a link 30; the latter has a slot, in which a pin 32 can be adjusted. and fixed, this pin being rotatably engaged with a roller 34-which can travel in a guide \Vhen the frame is swung the frame 10, with the work holders 9, is tilted on the pin 32, acting as a fulcrum, this pin being adjusted as required in the link 30.

For rotation of the work holders about their transverse axes, or about axes close thereto, the frame 10 has a slotted arm 35 in which a stud 36 can be adjusted and fixed. This stud 36 can engage between either of two pairs of parallel, vertically adjustable bars 37 so that by moving the work holder 14 the operator can rock the frame 10 into the position shown in Fig. 6, and can also rock it about the stud 36 when the latter is engaging the lower pair of bars 37. The bars 37 can be rotated on a vertical spindle 38, enabling them to be folded back, and retained by a catch 39, when not in use.

If, for example, after rocking the frame on the spindle 32 (Figs. at and 5), it is to be rocked about the stud 36,the pin 31 is withdrawn from the hole 31 (Fig. 6), and then the bars 37 are n'ioved into the position shown in Fig. (3.

Figs. 9 and 10 show inecbanisn'ifor lock ing the frame 10 after :uljustment. The frame 10 carries an are shaped member [0 against which a shoe '13 can be .)resse l by means of lever mechanism all, 42-. The frame 10 is locked by this means before the shaft 3 with its associated mechanism is moved towards the drills 5 .5. The pressure is applied by means of a treadle 46 and the levers 41 and 42, which move the shoe 43 in a guide 47 carried by the shaft-,and when the shoe encounters resistance the mechanism associated'with the shaft is pulled forwards.

To prevent lateral rocking of the frame 10 when drilling laterally inclined holes there is a pawl 48 pivoted to the guide 47 and adapted toengage the member 40. For

lateral movement of the frame 10 the pawl must be lifted, as indicated by broken lines in Fig. '9. a

The machine enables brush stocks of any kind to be drilled longitudinally and parallel or from the centre in either direction, with holes distributed in any way, at varying angles, including angles much more acute than is usual. The stocks may be used for hair and clothes brushes, scrubbing brushes,- carpet brushes, brooms, brewers brushes, nail brushes, including concave brushes, and so on. i
